  • Processes Of Ore Formation

    Figure 1 Iron pellets The pelletizing process is a process which contains numerous sub processes or process segments On the way from the mine to a final product the iron ore goes through the following main process segments 1) The iron ore is crushed and the waste rock is removed.First the raw materials either iron ore or scrap iron (depending on the process) are converted into molten steel The ore based process uses a blast furnace or smelter and the scrap based process uses an electric arc furnace Next the molten steel is poured and solidified in a continuous caster.
